Wearables, AI agents, and companion rings frequently request OS notification access. Audit what telemetry and personal credentials leak across listener APIs, test redaction rules, and export a strict zero-leak profile.
Export verified JSON audit logs or policy configuration for MDM/Android Enterprise profiles.
When hardware makers claim an AI or wearable "doesn't read notifications," they often refer to machine learning model prompts. However, companion mobile apps require full OS-level notification bridge permissions to relay vibration haptics and caller IDs, effectively capturing plain-text SMS 2FA codes, chat messages, and medical reminders into persistent SQLite databases.
On Android, NotificationListenerService provides unrestricted access to the entire notification payload including inline text reply actions and pending intents. Apple's ANCS operates over Bluetooth LE with strict attribute masking, but still reveals notification categories, titles, and subtitle strings unless disabled per app.
To isolate AI agents and smart rings from sensitive workflows, enforce on-device filter daemons that scrub 6-digit cryptographic tokens, strip Contact lookup IDs, and drop RemoteInput reply actions before Bluetooth packets leave the local handset.
